Abstract
A signal structure is disclosed. The signal structure may include a housing and a light head disposed within the housing. The light head may include at least one signal light mounted thereto. The signal structure may also include at least one actuator operatively coupled to the light head and configured to move the light head within the housing.
Claims20
A signal structure, comprising:
- a housing;
- a light head disposed within the housing, the light head including at least one signal light mounted thereto;
- and
- at least one actuator operatively coupled to the light head and configured to move the light head within the housing.
A signal structure, comprising:
- a light head;
- a signal light mounted to the light head;
- a stationary housing enclosing the light head and the signal light;
- at least one electric actuator operatively coupled to the light head and configured to move the light head within the stationary housing;
- and
- a controller in operative communication with the at least one electric actuator, the controller configured to move the light head within the stationary housing according to input received from an operator.
A method for moving a light head within a stationary housing of a signal structure, the light head operatively coupled to an actuator including a motor in communication with a controller, the method comprising:
- receiving an input signal to move the light head within the stationary housing;
- sending a signal to the motor to drive the actuator based on the input signal, the receiving and sending being performed by the controller;
- and
- moving the light head within the stationary housing, the moving being performed by the actuator.
